Hi, from what I understand a taC could be 20-30 enb. It can have different rac as 3g. But if csfb is to 3g, ensure that each tac have only one 3g lac.
Though for simplicity, that is what I did, the lac split into 2 rac and same have been done on 4g. Talist is the lac and tac is the rac
Ta list is a combination of tac
